The CAS Registry Mumber 2891-49-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 1 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2891-49: (6*2)+(5*8)+(4*9)+(3*1)+(2*4)+(1*9)=108 108 % 10 = 8 So 2891-49-8 is a valid CAS Registry Number.
